An administrator would like to set up Host Profiles in a vSphere architecture. Using the vSphere Client, the administrator connects to vCenter Server and navigates to Management, then begins to build a new Host Profile. Which of the following could explain why the administrator is unable to save the completed profile?

Answer: The administrator does not have the proper vSphere edition so this feature is not licensed

Explanation:
+ If a license exists for Host Profiles, the option will exist even if no ESX hosts have been added to vCenter Server
+ While a Host Profile can be applied to a cluster to check newly added hosts for compliance, profiles can also be applied to individual ESX Hosts. Host Profiles requires a license that is not available in all vSphere editions, and if a license is not present the option is unavailable.
Host Profiles does not rely on a service. However, the feature requires a license that is not available in all vSphere editions, and if a license is not present the option is unavailable.
